3.4

Contract Volumes and Excess Deliveries.

3.4.1

Transitional Contract Volume.

	(a)		Initial Deliveries and Pressures. Commencing with the effective date of the Agreement (“Effective Date”), SELLER may deliver up to 3,000 Mcf/d at the Receipt Point specified in the Agreement at pressures sufficient to enter BUYER’s system. BUYER estimates the line pressure to range between 95-150 psig. Simultaneously, BUYER will (i) commence acquisition of a site for a compressor station to be located in Section 59, Block M-l, H&GN Survey, Hemphill County, Texas downstream of the Receipt Point and (ii) initiate the necessary permitting process for the future installation of compression facilities at such site.
	(b)		High Pressure Deliveries. Commencing no later than ten (10) days after the volume delivered at the Receipt Point(s) equals 3,000 Mcf/d, BUYER will proceed to modify its system so as to provide delivery capacity to SELLER at the Receipt Point(s) of up to 10,000 Mcf/d at pressures of approximately 450 psig.
	(c)		Reduced Pressure Deliveries. At any time after the Effective Date at such time as SELLER’S daily volume exceeds 3,000 Mcf/d, SELLER may notify BUYER of SELLER’s desire that BUYER install compression facilities in order for BUYER accept deliveries consistent with the volume and pressure provisions of the 3.4.2 and 6.1 hereof. SELLER will provide all necessary projections of future production in order for BUYER to maximize the efficiency of its compression facilities consistent with its contract obligations. No less than four (4) months following the receipt of SELLER’s notice, BUYER will be prepared to take deliveries of natural gas under this Agreement pursuant to such provisions.

	3.4.2		Permanent Contract Volume. Following the installation of the facilities set forth in 3.4.1(c), above, SELLER shall deliver and sell and BUYER shall receive and purchase at the Receipt Point(s) all of SELLER’s Gas developed and produced from the Dedicated Wells up to a volume of 15,000 Mcf/d (the “Contract Volume”). These volumes are to be delivered consistent with the pressure requirements set forth in section 6.1.
	3.4.3.		Additional Gas. Gas tendered for delivery to BUYER at the Receipt Point(s) in excess of the Contract Volume shall be deemed “Additional Gas”. BUYER shall use its best reasonable efforts to purchase all Additional Gas tendered for delivery by SELLER. In the event BUYER is unable to take any portion of the Additional Gas, such portion (“Excess Gas”) shall be released from the terms of this Agreement until and unless, within thirty (30) days of such release BUYER notifies SELLER of intent to take and purchase such Excess Gas under the terms of this Agreement and the date upon which such receipts are to commence, provided such receipts are to commence no later than ninety (90) days from the date of BUYER’s notice, and subject to Seller’s prior nominations, which nominations

shall not exceed a one-month period. Failure to provide notice to SELLER of its intent to take such Excess Gas shall be deemed a permanent release of such Gas.

IV. RESERVATIONS OF SELLER AND BUYER

4.1

SELLER’s Reservations.

	4.1.1		To operate said Leases and/or Wells free from control by BUYER in such manner as SELLER, in SELLER’s sole discretion, may deem advisable, including, without limitation, the right to drill new Wells, to repair and rework old Wells, and to abandon any Well or surrender any Lease when no longer deemed to be capable of producing Gas in commercial paying quantities under normal methods of operation by SELLER.
	4.1.2		To unitize or pool any of the Leases or portions thereof with other Leases, in such event SELLER’s interest in the unit and the unit Gas attributable to SELLER’s interest shall be subject to and SELLER agrees to take all action necessary to commit such unit Gas attributable to SELLER’s interest to this Agreement.
	4.1.3		To retain all liquids and Condensate separated from the Gas by the use of typical volumetric (non-refrigerated) oil and Gas separators prior to the delivery of the Gas to BUYER at the Receipt Point(s) specified herein.

4.2

BUYER’s Reservations.

	4.2.1		Processing Rights. SELLER does hereby grant, assign, and convey to BUYER exclusive processing rights for the recovery of Plant Products for Gas delivered to BUYER for processing at the Receipt Point(s). SELLER shall not process the Gas or allow the Gas to be processed prior to Receipt by BUYER hereunder for processing.
	4.2.2		Condensate. Condensate recovered by BUYER downstream of the Receipt Point(s) shall belong to BUYER. Title to the Condensate shall pass to BUYER upon its recovery by BUYER and shall be free and clear of all liens, claims, and encumbrances created by, through or under SELLER.
	4.2.3		Uneconomic Conditions. The purchase of Gas under the terms of this Agreement will be deemed uneconomic as follows:

	(a)		The purchase of SELLER’s Gas from any Receipt Point shall be uneconomic if and to the extent BUYER’s net revenue derived from the purchase and resale of such Gas and associated products is less than BUYER’s actual average operating costs associated with the gathering, compression and processing of such Gas, excluding any allowance for depreciation or return on investment of BUYER’s plant and equipment. In such event, BUYER shall offer SELLER pricing terms for such uneconomic gas at which such conditions do not exist, in which event SELLER may either (i) accept such revised pricing terms for so long as such uneconomic condition exists or (ii) have the uneconomic gas released from this Agreement.
	(b)		An “uneconomic Plant” condition shall be deemed to exist if BUYER determines that the continued operation of BUYER’s gathering and processing facilities with respect to the purchase, gathering and/or processing of all gas collectively behind BUYER’s Plant results in BUYER being unable to recover its actual costs in the operation of such facilities for a period of three consecutive calendar months. In the event of an “uneconomic Plant” condition, BUYER may elect to terminate gathering and plant processing operations upon ninety (90) days prior written notice to SELLER, at which time this Agreement shall terminate.

V. QUALITY OF DELIVERED GAS

5.1		The Gas delivered at the Receipt Point(s) shall meet the quality specifications defined in Exhibit “C” attached hereto.
5.2		SELLER shall not connect any well that would cause the Gas to be delivered to BUYER at the Receipt Point(s) to fail to conform to the specifications set forth on Exhibit “C”.

In the event SELLER wishes to connect any Well which would cause the Gas at the Receipt Point(s) to fail to conform with such specifications (“Non-Conforming Well”) SELLER shall notify BUYER of its desire to tender gas from a Non-Conforming Well at which time BUYER may elect to either:

	(a)		accept Gas from such well without modification or treatment,
	(b)		seek agreement with SELLER upon a means of treating the gas from such well and the fees (if any) to be charged therefor prior to the flow of gas from such well under this Agreement, or
	(c)		release such Non-Conforming Well from this Agreement.

5.2.2

In the event the quality of SELLER’s Gas generally fails to meet the specifications, SELLER shall notify BUYER prior to the delivery of such Gas. Upon receipt of SELLER’s notice BUYER and SELLER shall endeavor to agree upon a means to bring such gas into compliance with the specifications and a fee (if any) therefore. Failing such agreement, BUYER may either accept such Gas “as is” or release such Gas from this Agreement.

5.3

BUYER’s acceptance of Gas that does not conform to quality specifications set forth herein will not constitute a waiver of SELLER’s obligation to conform to such specifications in the future, nor a waiver of BUYER’s right to refuse delivery of such nonconforming Gas at any time.

VI. DELIVERY, COMPRESSION, PRESSURES, METER
FEES, REBUILD AND ALTERATIONS

6.1		Delivery Pressures. Commencing with the installation of facilities pursuant to 3.4.1(c) hereof, SELLER shall deliver Gas to BUYER at the Receipt Point(s) at a pressure sufficient to enter BUYER’s system against the operating pressure as it exists from time-to-time, but not to exceed 150 psig.
6.2		Pressures. Pressures calculated for purposes of this Agreement shall be volume-weighted pressures at the Receipt Point(s) for the Month as determined by BUYER.
6.3		Meter Fees. In the event that the total metered volume from any one (1) Receipt Point falls below an average of twenty-five (25) MCF per day for any month, BUYER shall charge SELLER a meter fee for each MCF delivered by or for the account of SELLER for that month. The meter fee shall be determined by dividing a sum of (**) Dollars ($(**)) by the total metered volume (MCF) for that month. In the event the total metered volume is zero (0) the fee shall be (**) Dollars ($(**)) multiplied by SELLER’s owned or controlled interest.
6.4		Rebuild and Alterations. BUYER reserves the right, in its sole discretion, to alter, repair, maintain, expand or rebuild, without approval of SELLER, any portion of BUYER’s facilities. SELLER shall make no alterations, additions or repairs to or on the facilities of BUYER. SELLER agrees not to connect or cause the connection of any third-party well to BUYER’s facilities for any purpose without the express written consent of BUYER, such consent to be in BUYER’s sole discretion. If this condition is breached by SELLER, BUYER shall have the right

and option, notwithstanding any other provision of this Agreement, to terminate this Agreement immediately and without further obligation to SELLER.

VII. NOMINATIONS AND SCHEDULING

7.1

Deliveries. SELLER shall deliver all available Gas in such uniform hourly flows as is commercially practicable. In the event SELLER anticipates a material increase or decrease in the flow of Gas at any Receipt Point, SELLER shall provide BUYER with at least five (5) days advance notice of change.

VIII. PAYMENT, EXAMINATION,
INDEMNIFICATION, SUSPENSION, AND DEDUCTIONS

8.1		Payment. BUYER shall, on the later of (i) the last day of the month or (ii) within ten (10) days of BUYER’s receipt of any necessary allocation statements relating to sales and purchases from third parties upstream of the Receipt Point(s), pay SELLER for the Gas delivered hereunder during the preceding month. During any period BUYER purchases Gas from SELLER and other SELLER(s) delivered to any Receipt Point(s), SELLER shall furnish, or cause to be furnished, to BUYER on or before the fifteenth (15th) day of each calendar month, any necessary allocation statements containing data (including, but not limited to, quantity and BTU content) that BUYER may require to enable BUYER to make payments. SELLER is to cooperate with other SELLER(s) delivering Gas at the Receipt Point(s) in order to appoint in writing a representative who, as their agent, is to furnish an allocation statement. BUYER is entitled to rely conclusively on such allocation statement, and has a complete defense to any claim by SELLER for any sums due for Gas delivered by SELLER at the Receipt Point(s) during any period by showing that BUYER has made payment to SELLER for its share, as identified in such allocation statement, of the total quantity of Gas received by BUYER at the applicable Receipt Point(s) during the period in question (other than for measurement error as specified in the Article titled MEASUREMENT OF GAS VOLUME AND TESTING). If any allocation statement is not furnished to BUYER by the fifteenth (15th) day of any month, the time that BUYER has to make payment for delivered Gas (without interest) is to be extended until the payment cycle which next follows the tenth (10th) day after BUYER’s receipt of the allocation statement.
8.2		Final Payment. All payments under this Agreement will be final unless questioned by either party within two (2) years of the due date of a payment.
8.3		Examination of Records. Each party to this Agreement shall have the right, at any and all reasonable times during normal business hours, to examine the books and records of the other party, to the extent necessary to verify the accuracy of any statement, charge, computation, or demand made under or pursuant to this Agreement, and both parties shall keep all such records for at least twenty-four (24) months after the due date for payment for the Receipt of Gas to which such records are applicable. Such books and records shall be conclusively presumed to be correct, except as to claims or corrections by the parties made by written notice to the other within such twenty-four (24) month period.
8.4		Indemnification, Payment Suspension. Each party agrees to indemnify and hold the other party harmless with respect to all costs, losses, and damages (including without limitation reasonable attorney’s fees) arising from or related to the breach of any covenant, representation, or warranty contained in this Agreement. In the event of any claim arising from or relating to such a breach by SELLER, BUYER shall be entitled, at its option, in addition to any other rights it may have, to suspend payment of sums due SELLER hereunder up to the amount of such claim

		until such claim is resolved or until such time as SELLER provides sureties acceptable to BUYER. Any such suspension of payment hereunder shall not constitute a breach of BUYER’s payment obligations under this Agreement.
8.5		Deductions. BUYER shall also be entitled, at its option, in addition to any other rights it may have, to deduct from any payment due SELLER under this Agreement any amounts payable to BUYER from SELLER under this Agreement and to apply such amounts deducted to pay such amounts payable to BUYER, and such deduction and application shall not constitute a breach of BUYER’s payment obligations under this Agreement.
8.6		Reimbursement of State Severance Taxes. The payment set forth on Exhibit “A” for gas purchased by BUYER hereunder shall be deemed to be inclusive of reimbursement to SELLER for production and severance taxes borne by SELLER. No additional payment from BUYER to SELLER hereunder, other than that specified on Exhibit “A”, shall be required to compensate SELLER for such tax reimbursement.

IX. WARRANTY, TITLE, AND EASEMENTS

9.1		Warranty of Title. SELLER warrants that it has the title to the Gas dedicated hereunder and delivered at the Receipt Point(s), and said Gas is free from all liens and adverse claims of all kinds, including the right and authority to sell and to process for the recovery of Plant Products. SELLER shall hold BUYER harmless against adverse claims related thereto.
9.2		Title. Title shall pass to BUYER at the Receipt Point(s).
9.3		Easements. To the extent SELLER has the right to do so, SELLER hereby permits BUYER the rights of ingress and egress on the Leases to construct, install, operate, repair, inspect and maintain BUYER’s facilities necessary to receive Gas from SELLER at the Receipt Point(s). SELLER hereby assigns and grants to BUYER, to the extent it has the right to do so, an easement and right-of-way upon all lands covered by the Leases for the purposes above. Any property of BUYER placed in or upon any of those lands shall remain the personal property of BUYER, and may be disconnected and removed at any time. SELLER shall, at its expense, maintain and provide all such easements, rights-of-way, lease roads and other facilities upon such Leases as may reasonably be deemed necessary by BUYER for its performance of this Agreement. SELLER further agrees to indemnify BUYER from any adverse claims related thereto.

X. INDEMNITY, INTERRUPTION, AND FORCE MAJEURE

10.1		Indemnity. In addition to the indemnities contained herein, BUYER shall indemnify and hold SELLER harmless against any claims for damages arising out of the operations conducted hereunder by BUYER. Likewise, SELLER shall indemnify and hold BUYER harmless against any claims for damages arising out of SELLER’s operations hereunder. The obligations of the parties under this Agreement are obligations of the parties only and no recourse or remedy shall be available against any officer, director, or employee representative of a party or against any affiliate of a party.
10.2		Interruption. It is understood and agreed that either party hereto may, without liability to the other party, interrupt the operations of its facilities for the purpose of making necessary alterations, maintenance, or repairs thereto, but that such interruption shall be for only such time as may be commercially reasonable to perform such operations. Delivery and/or receipt of Gas pursuant to this Agreement may be suspended for such period of interruption.
10.3		Force Majeure. If SELLER or BUYER is rendered unable, wholly or in part, by reason of force majeure, from carrying out its obligations under this Agreement (other than the obligation to make payment of amounts due hereunder), then upon said party’s giving prompt written

notice of such force majeure to the other party, the obligations of the party giving such notice, so far as they are affected by such force majeure, shall be suspended during the continuance of any inability so caused, but for no longer period, and such cause shall be remedied with all commercially reasonable dispatch. The term “force majeure,” as used herein, shall include acts of God; acts of federal, state, or local government or any agencies thereof; compliance with rules, regulations, permits or orders of any governmental authority or any office, department, agency, or instrumentality thereof; strikes, lockouts, or other industrial disturbances; acts of the public enemy, wars, blockages, insurrections, riots, and epidemics; landslides, lightning, earthquakes, fires, storms, floods, and washouts; arrests and restraint of people; civil disturbances; explosions, leakage, breakage, or accident to equipment or pipes; freezing of Wells or pipes; weather-related shutdowns; inability to secure rights-of-way; inability to timely obtain equipment, supplies, materials, permits, labor; failures or delays in transportation; receipt of non-specification or non-merchantable Gas; and any other causes, whether of the kind herein enumerated or otherwise, not within the reasonable control of the party claiming suspension, which, by the exercise of due diligence, such party shall not have been able to avoid. The settlement of strikes or lockouts shall be entirely within the discretion of the party having the difficulty. The requirement that any force majeure shall be remedied with all commercially reasonable dispatch shall not require the settlement of strikes or lockouts by acceding to the demands of the opposing party, when such is deemed inadvisable by the party involved.

XI. ROYALTY AND TAXES

11.1		Royalty. SELLER shall account for, pay, or cause to be paid all royalties, overrides, and other sums due by SELLER to the owners of the mineral, royalty, and other interests in the Gas, and SELLER shall indemnify and save BUYER harmless against all loss, damage, and expense of every character on account of adverse claims to all such Gas, Residue Gas, and Plant Products or royalties, taxes, payments, or other charges due thereon. Should BUYER be obligated by law or regulation to make payment for any royalties or overrides due to be paid by SELLER, BUYER shall deduct such payments from any amounts due by BUYER to SELLER. Should such payments be in excess of amounts due by BUYER to SELLER, SELLER shall promptly reimburse BUYER for the amount of royalties or overrides so paid within ten (10) days of receipt of such statement
11.2		Taxes. SELLER shall pay or cause to be paid any sales, transaction, occupation, service, production, severance, gathering, transmission, or excise taxes, assessments, or fees levied, assessed, or fixed, whether by the United States, the state, or other governmental agency, in respect of or applicable to the Gas delivered hereunder. Any taxes and statutory charges levied or assessed against SELLER’s properties, facilities, or operations shall be borne by SELLER. BUYER shall bear all taxes levied against its properties or facilities.

Should such payments be in excess of amounts due by BUYER to SELLER, SELLER shall promptly reimburse BUYER for the amount of taxes so paid within ten (10) days of receipt of such statement.

XII. MEASUREMENT OF GAS VOLUME AND TESTING

12.1

Calibration. BUYER shall keep its measurement equipment accurately calibrated and in repair, making tests at reasonable intervals of no less than once every calendar quarter. BUYER agrees to give SELLER reasonable notice of such tests of the measuring equipment so

		that, if SELLER desires, it may have its representative present. In the event the meters are found to be inaccurate, such meters will be adjusted to register accurately.
12.2		Accuracy. Each party shall have the right to challenge the accuracy of any related equipment and, when challenged, the equipment shall be tested, calibrated and repaired by BUYER; the cost of any such special test shall be borne by BUYER if the percentage of inaccuracy is found to be more than two percent (2%), but if the percentage of inaccuracy is found to be two percent (2%) or less, the cost of such special test shall be borne by SELLER. If, upon any test, the percentage of inaccuracy of the measuring equipment is found to be in excess of two percent (2%), registrations thereof and any payment based upon such registration shall be corrected for a period extending back to the time (not to exceed one (1) year) when such inaccuracy began, if such time is ascertainable, and if not ascertainable, then back one-half (1/2) of the time elapsed since the last date of calibration not exceeding, however, forty-five (45) days.
12.3		Repairs. If, for any reason, the meters are out of service or out of repair so that the amount of Gas delivered cannot be ascertained or computed from the reading thereof, the Gas delivered during the period such meters are out of service or out of repair shall be estimated and agreed upon by the parties hereto upon the basis of the data available using the first of the following methods that is feasible:

	12.3.1		By using the registration of any check meter or meters if installed and accurately registering, or in the absence of (12.3.1) then;
	12.3.2		By correcting the error if the percentage of error is ascertainable by calibration, special test, or mathematical calculation, or in the absence of both (12.3.1) and (12.3.2) then;
	12.3.3		By estimating the quantity of Gas delivered based on the registration of any meter or meters if installed and accurately registering, or in the absence of (12.3.1), (12.3.2), and (12.3.3) then;
	12.3.4		By estimating the quantity of Gas delivered or redelivered based on deliveries or redeliveries during preceding periods under similar conditions when the meter was registering accurately.

12.4		Records. The records from the measuring equipment shall remain the property of the party owning such equipment and shall be kept by such party on file for a period of not less than two (2) years. At any time within such period, such party shall, upon request to the other party, submit to such party records from the measuring equipment, together with calculations therefrom, for inspection and verification, subject to return within thirty (30) days from receipt thereof.
12.5		Measurement Standards. The measuring station or stations provided for hereunder shall be so equipped with meters, recording gauges, or other types of meter or meters of standard make and design used in the industry and according to applicable AGA or API standards, so as to accomplish the measurement of Gas delivered and redelivered hereunder. Gas measured hereunder will have its volume, mass, gravity, composition or energy content determined and computed in accordance with applicable AGA standards in effect at the date of installation of the measurement equipment and shall comply with applicable state and federal regulation. At BUYER’s option, BUYER may update the measurement equipment and/or the determination of volume, mass, gravity, composition or energy content in accordance with subsequent revisions, supplements, and appendices to said AGA standards.
12.6		Pulsation. The Parties shall design, install, operate and maintain their respective equipment in such a manner that pulsation-induced measurement error is minimized. Pulsation-induced error shall not exceed one quarter of one percent (0.25%) of square root error (SRE). Either party has the right to request a test of the orifice meter facility. If SRE is found to exceed the limit stated above, the party responsible for the creation of the SRE must have a plan for the

		elimination of the SRE within thirty (30) days and equipment installed or modified to correct SRE in a reasonable amount of time, not to exceed six (6) months. Pulsation errors determined by the use of a square root error indicator manufactured under a license for the Southern Gas Association are to be used only for the purpose of determining SRE and are not to be used for adjusting measured volumes.
12.7		Boyle’s Law. The measurement hereunder shall be corrected for deviation from Boyle’s Law at the pressures and temperatures under which Gas is delivered hereunder.
12.8		Temperature. The temperature of the Gas shall be determined to the nearest one degree Fahrenheit (1°F) at the points of measurement by the continuous use of recording thermometers of standard manufacture acceptable to the parties, to be installed in accordance with the recommendations contained in American Gas Association Measurement Committee Report Number 3, 7, or 9 as appropriate, and the arithmetical average of hourly temperatures of the Gas so determined each day shall be used in computing temperatures of the Gas during each day.
12.9		Supercompressibility. Unless otherwise allowed by state law, adjustment for the effect of supercompressibility shall be determined by test or by mutual consent of the parties hereto according to the provisions contained in American Gas Association Measurement Committee Report Number 3, 7, 8 or 9 as appropriate, for the average conditions of pressure, flowing temperature, and specific gravity at which the Gas was measured during the period under consideration and with the respective proportionate values for carbon dioxide and nitrogen fractional values and to obtain subsequent values of these Components as may be required from time to time.
12.10		Check Measurement. At the Receipt Point(s) SELLER may install check measuring equipment at its own cost and expense; provided, such equipment shall be so installed as not to interfere with the operations of the BUYER. BUYER’s meter shall be the meter used for all measurement purposes. BUYER and SELLER, in the presence of each other, shall have access to the other’s measuring equipment at all reasonable times; but the reading, calibrating, and adjusting thereof, and the changing of charts, if any, shall be done only by the owner of the meter or its representative unless otherwise agreed. Each party shall give notice sufficiently in advance, and the other parties notified shall have the right to be present at the time of any installing, reading, cleaning, changing, repairing, inspecting, testing, calibrating, or adjusting done in connection with the other’s measuring equipment; provided, however, failure of either party so notified to witness such an operation after due notification shall not affect the validity of such operation in any way.
12.11		Sampling. BUYER shall obtain a sample at least annually of Gas at the Receipt Point(s) by using methods contained in GPA Standard 2166 / API 14.1, as revised, “Methods for Obtaining Natural Gas Samples for Analysis by Gas Chromatography.” This sample may be obtained utilizing a spot sampler, continuous sampler, on-stream chromatograph or other instruments approved by BUYER. SELLER may request that additional samples be taken in order that SELLER may have its own sample tested independently. Any additional samples requested by SELLER shall be at SELLER’s sole expense.
12.12		Composition, Gross Heating Value, Specific Gravity. The composition of the Gas shall be determined from the sample of the Gas by using GPA Standard 2261, as revised, “Method of Analysis for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography,” with the exception of sulfur compounds. The gallons per MCF and the Gross Heating Value of the Gas shall be determined by using technically correct methods contained in GPA Standard 2172, as revised, “Method for Calculation of Gross Heating Value, Specific Gravity, and Compressibility of Natural Gas Mixtures from Compositional Analysis”, and the Gross Heating Values from GPA Standard 2145, as revised from time to time, “Table of Physical Constants
